The present invention relates to improvements in anti-rattling devices such as for automobile panes, and more particularly the sliding door and window panes. employed in the closed type of machines. f

- According tothe present ple and cheaply constructed device is provided which may be readily attached by suitable supporting members 'to any type of door or[ window panes, so that its operat- Figure 1 is a horizontal sectionalviewi through ad'automobil'e pane and its casing,

, that 'this felt is not suflicient to constantly exert a deadeninglpressure upon the pane,--.

In Fig. 1,v the casing 110 has a recess 11 therein with a' groove 12 to support a felt 13; which fits arounda vertical edge of the pane'14. It has been found in "practice but the latterfsoonbecomes free to move in the felt, and 'thus to cause a rattling and invention, a sim-" atthe other end, usually tion of a washer 34.

A base plate20 hasan outwardly turned flange 21 which fits on one side of the easing At the opposite side of'the base plate is an upstanding lug 22 to receive the clamping screws 23 which pass through and have their heads supported against the lug 24 on a second clampingme'mber 25. This second clamping member has slots 26 therein ,(Fig. 2) to receive the guiding rivets 27 which permit and "cause this base plate. 20

and the clamping plate to move in planes,

parallel one to another.; The intermediate portion ofthe clampingplate 25 is rebent in a'loop 25a, and the clamping plate ter-' minates 'withan engaging portion or flange 28 whichifits beneath a head on the casing 10. As the screws 23*fare drawn tight, the

clamping'porti'ons or' flanges 21, 28 clamp) thefcasing 10 between them and thussecure the base plate 207firmlyin position at the casing edge. The base plate 20': also has theiupstandingfingers 30 which are formed integrally 'by'punching from the base plate 20, and have apertures alinement therethrough to receive"the"guide"0r pivot pin 31, which has an enlarged head 32'at one end, and receives a retaining cotter] pin 33 with the interposi- A spring actuated sector'plate has a stop foot 36 to engage 'the base plate 20 and thus limit its movement, of springeffected rockingin a counterclockwise direction in 4 'Fig. 1. This spring-actuatedsector 35 also 7 I has-anextendingnose 37 which passes over the loop 38 of a spring 39 which is formed into symmetrical convolutionsfadjacent its endsiw These convolutlons are arranged aroundthe pivot pin 31, respectively, be-,

tween thehead 32 and 'one' of the upstanding I fingers 30, and'between the washer 34: and theother upstanding finger. The extreme ends 40 of the spring rest against the fingers:

30L It is apparent thatfthe' spring 39 constantly exerts'a pressure upon the sector 35 and tends to; cause the same: to turn in a counterclockwise direction in- Fig. 1.

:p. An extendingarm 41 is 'likewise pivoted about the pin 31, and at its end has a rivet 42 serving as a stiflj' pivotal mounting for a shackle 43 having an axle 44 therein for the anti-friction roller 45, which preferably is formed of fibre or similar relatively soft but resistant material.

The extending arm 41 receives a screw 46 which passes through an arcuate slot 47 in the sector 35, this slot being concentric with the axis of the pivot pin 31.

In locating this form of the device upon an automobile casing for anti-rattling employment in conjunction with the pane therein, the clamping flanges 31, 28 are brought into contact with the edge of the casing 10 in the manner described above. The screw 46 is then loosened, and the pane 14 brought to a position opposite the roller 45, and this roller is brought down against the pane by rocking the extension. 41 with respect to the sector 35: the axle 44 is carefully alined to be parallel to the plane of the pane. The roller 45 is pressed forcibly against the pane 14 until the latter is driven into solid contact with the opposite side of the felt 13: the screw 46 may now be tightened; and the device is ready for use. If it is desired to secure a slightly greater spring pressure upon the roller 45, the pane 14 may be dropped, the screw 46 loosened and the arm 41 rocked slightly further in a counterclockwise direction: when the screw 46 is again tightened, the desired pressure will have been obtained.

During the raising and lowering of the pane 14 the relative pressure toward the right in Fig. 1 from this pane upon the roller 45 may cause the sector 35 to be rocked in a clockwise direction slightly, against the action of the spring 39: thus maintaining the anti friction effect. It will be noted that when the pane 14 is. entirely removed from opposite the roller 45, the stop 36 prevents excessive movement of the arm 41.

In the simplified form of the mounting shown in Fig. 3, the base plate 20a is formed simply with a retaining means, which in the present instance comprises the end braces 205 having apertures 200 therein to receive securing screws. The other parts of this construction are the same as before, its operation is the same: and it will be noted that by reason of the simple arrangement, the device is even cheaper in construction, although it may not be so readily placed and removed as the device of Figs. 1 and 2.
